These posts one side as they travel. Supported by the extend upwardly and are bent laterally in a axles and wheels is a carriage frame 15, which horizontal direction to form cross arms 2. has extending downwardly from each side.

brackets 16 that have slots 17 therein to receive the ends of the axles. There are as many of these brackets as there are axle ends so that the frame is supported by the ends of the axles.

Located on each side of the carriage frame adjacent one of the axles is a bearing 18 for supporting a paddle shaft 19. This paddle shaft is in two sections, the upper section being supported by the bearing and the lower section supported by the upper section. The

upper section is hollow and has in one side thereof a bayonet slot 20. The lower section 21 fits within the upper section and is adapted to slide up and down therein, with a pin 22 fitting in the slot 20. In Figure 3'the parts of the stirrer shaft are shown in stirring or'lowerpositi'on. 1

Whenever the part 21 is elevated so that the pin 22 is brought into the bayonet part of the slot, by moving the stirrer 23 about ninety degrees the. lower part of the shaft is supported by the upper part in elevated position. On thelower end of each lower section of the stirrer shaft is a stirrer paddle 23. I On the upper end of each paddle. shaft is a sprocket wheel 24 firmly attached thereto for rotating the stirrer shaft and the stirrer paddle on the lower endthereof.

Extending. downwardly from the carriage frame is a bearing 25 in whichia vertical shaft 26'is located. On the upper end of this shaft is a pair of sprocket wheels 27, while on the lower end is .a' guide roller 28 for engaging the guide 11 and the loops 12 in the forward and lateral movements ofthe carriage frame. Just above the guide roller 28 andattached rigidly to the shaft 26 is a pinion 29 which meshes with the teeth onthe rack bar 10 so that as the shaft 26 rotates the carriage frame will be moved along the trackway, and as it gets to the end of the bar 10 will be guided around and onto the other side of the rack bar. This guiding is effected by means of the loop around the bar 10 and by the loops at the ends of the guide 11.

The upper end of the shaft 26 is supported by abracket 30, as shown in Figure 2. Lo-

cated at a suitable point on the shaft 26 is a worm gear 31 engaged by a worm 83 on the motor shaft 32, and connecting one of the sprockets on the shaft 26 to-the sprocket on V the upper end of the stirrer shaft is a sprocket chain 34:. There are two of these chains, one for each stirrer shaft, and the sprocket on the upper end thereof forconnecting it to one of the'sprockets on the shaft 26.

Extending downwardly from the frame is av post 35 which carries on the lower end thereof a roller '36. This roller is to engage the guide member 11 in the forward and backward movement of the apparatus on the tmckWa-y. This roller, in; cooperation with roller 28,. assists in keeping the carriage frame in proper transverse position while engaging the lower side of the rack bar 10.

The shaft 26 is rotating in such a direction that the carriage travels toward the left. When the pinion reaches the end of the rack bar 10 it travels around it and enters the space between it and the upper branch of the guide member so that the whole stirring apparatus is moved in a position toward the top of the drawings, and due to the continued operation of the pinion, the carriage frame travels toward the left.

As the carriage frame is shifting from one position to another position transversely of the trackway, the roller 36 passes around the righthand end of the guide member 11 and in so doing is guided by the loop 12 at the righthand end, as shown in Figure 1. This action continues until the carriage frame reaches the lefthand end, where the operation of the pinion and the rack tends to shift the carriage frame laterally so that it will travel then again toward the righthand end. It will be observed that the roller 38 is slightly offset longitudinally from the roller 28. This arrangement of the rollers assists in keeping the carriage frame in proper longitudinal arrangement in relation to the trackway, and assists; the wheels 1 in main taining the carriage frame in proper position. And it is in order to accommodate this relative change of positions that the loops at the ends of the bar 10 and the guide member 11 are offset longitudinally one with relation to the other, as distinctly shown in Figure 1 both at the righthand and the lefthand end thereof.

In order to secure a firm and solid structure the parts herein described and shown are welded one to the other, except such parts as are movable. All fixed parts are welded or may be united by any other suitable means. Preferably welding is used.

I desire to comprehend within my invention such modifications as may be embraced within my claims and the scope of my invention.
